AmiMoJo writes: The Ministry of Sound, a UK dance music brand, is suing Spotify because it has not removed user's playlists that mirror their compilation albums. The case will hinge on whether compilation albums qualify for copyright protection due to the selection and arrangement involved in putting them together. Spotify has the rights to stream all the tracks on the playlists in question, but the issue here is whether the compilation structure — the order of the songs — can be copyrighted.
